Can I Trust You?-A KotLC popstar au

A kotlc popstar au because I've only seen three in my whole life.

The Moonlark: A global pop sensation who's real identity is only known by her manager/producer known as Ruckleberries (Forkle), her DJ/backup singer known as Gears (Dex), her guitarist known as Shade (Tammy boy), her choreographer/pianist known as River (Linh), her drummer known as wildfire (Marella), her bassist known as Cheshire (Stina), and her family (Grady and Edaline/the Dizznee's).
Sophie Foster-Ruewen: A girl who's family was killed in a car crash and got adopted by a rich family, the Ruewen's. A girl who's only friends are her cousin, Dex, twins Tam and Linh Song, and two girls named Marella and Stina who live in a different country. A girl who's childhood best friend moved to a different country. A girl who's secretly a pop-sensation called Moonlark.
What will happen when Grady's work requires him to move back to a small country called The Lost Cities? What will happen when Sophie gets enrolled into a fancy school named after a fungus? What will happen when she finds her childhood best friend there? What will happen when she starts to make friends? Will her secret stay safe, or will the truth come out?

Ok that description sucked but the story (probably) won't be that bad. Please don't be rude if the story sucks, this is my first fanfiction.
